CLI NKER TONGS Filed May 7. 1954 ATTOR N EY Patented Aug. 27, 1935UNITED STATES PATENT OFFICE Claims.

This invention relates tol clinker tongs, and more particularly to aclinker tongs adapted for use in connection with large firing equipment.

An object of the invention is to--provide a novel 5 clinker tongsadapted for the efficient removal of clinkers of various sizes notconveniently extractable with devices ofthe type now in use.

`A further object of the invention is to provide in a device of thetype, a releasable lock for the jaws thereof, in varying juxtaposition.

Other and further objects of the invention will appear as thedescription proceeds, reference being had to the accompanying drawing,in Which:-

l5 Fig. 1 is a fragmentary plan view in perspective of a clinker tongsembodying my invention.

Fig. 2 is a side view in elevation of the device.

Fig. 3 is a detail View in elevation of the lock.

Referring more particularly to the drawing, the

numeral lil represents a tubular member forming the body of the device.At the upper end of the tube is a circular flange I I, forming a part ofa locking device to be later described. A jaw, I2, of multiple arcuateform, is xed to the lower end of the tubular member I0, and is bent atthe point of attachment to form an obtuse angle in the relation of itsbody with the tubular member I0.

The arcs, I3, in the jaw I2, are graduated progressively larger from thepoint of the jaw to its attached end. A rod, I4, is journalled withinthe tube I 0, and terminates in an integral jaw I5, which latter has astructure opposing and complementary to that of the jaw I 2. The jaw I 5is bent to form an obtuse angle with rod I4, to conform exactly with theangular relationship of jaw I2 and tubular member I0.

The flange I I is perforated as at I6, to act as a keeper for the bolt Isupported in housing I8 attached to the rod handle I9. A coil expansionspring 20 impels the bolt I'I normally downwardly. The bolt handle 2l isprovided for manual withdrawal of the bolt I'I.

In operation, the bolt Il is withdrawn to permit opening of the jaws I2and I5. A clinker may be grasped between the arcs I3 of the proper size,and after the jaws are turned tight, the bolt I'I may be releasedwhereupon it will lock in one of the perforations I6. The tool may thenbe withdrawn with the clinker securely locked therein.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, is:-

1. A clinker tongs comprising a tubular portion and a rod memberturnable therein, an extension of said rod member bent to form a handle,an opposite extension of said rod member forming a jaw member having aplurality of joined inwardly convex arcs progressively varying in size,and a complementary jaw member formed on the end of said tubular portionfor cooperation with said rod jaw member.

2. A clinker tongs comprising a tubularportion and a rod member turnabletherein, an extension of said rod member bent to form a handle, anopposite oblique extension' of said rod member forming a jaw memberhaving a plurality of joined inwardly convex arcs progressively varyingin size, and a complementary jaw member formed on the end of saidtubular portion for cooperation with saidrod jaw member.

3. A clinker tongs comprising a tubular portion and a rod memberturnable therein, an extension of said rod member bent to form acircular handle, an opposite extension of said rod member disposed at anangle thereto forming a jaw member having a plurality of joined inwardlyconvex arcs progressively varying in size, and a complementaryjaw memberformed on the end of the said tubular portion for cooperation with saidrod jaw member.

4. A clinker tongs comprising a tubular portion and a rod memberturnable therein, an extension of said rod member bent to form acircular handle, an opposite oblique extension of said rod memberforming a jaw member having a plurality oi joined inwardly convex arcsprogressively reduced in size, and a complementary jaw mem- 35 berformed on the end of said tubular portion for cooperation with said rodjaw member.

5. In combination, a tubular member, a rod member 'turnable therein, anextension of said rod member bent to form a circular handle, an oppositeoblique extension of said rod member forming a jaw member having aplurality of joined inwardly convex arcs progressively reduced in size,and a complementary jaw member formed on the end of said tubular portionfor cooperation 45 with said rod jaw member, a lock housing on said rodmember adjacent the handle, a bolt therein, spring means for said bolt,and a circular ange on said tubular member having spaced perforationsadapted to receive the bolt. 50
